file permissions on redhat linux

sandyt — Mon, 08 Feb 2010 13:58:14 GMT

I am having trouble doing the following on a redhat linux server.

1. we have a library aaa.
2. I want users x,y, and z to be able to write
to that library.
3. I want user x to only be able to delete his own files, while other users can have full rights on all files in the library regardless of owner or group.
4. User x is only a member of his group. Users y and z are members of another group.
5. I tried putting a sticky bit on the others permission on the library, but that causes problems with the other users.

Shalom,

Item 5.

What kind of problems. Post command and error response.

Suggestion:

Give the group y and z are members of full rights to the directory.

Give group of user x read execute only.

Perhaps create a common group for management of this project/folder/library

In this case you need a separate folder for user x and user y/z, or give user y/z the rm command with sudo power for that folder. You'll need the SGID bit on the directory.

the sticky bit should go on the directory, not the file.

You could also dig into SELinux, as fine grained ACLs would give you flexibility to do exactly what you want.

Thanks for the input. I am using seperate folders as Ivan suggested in the short term, but plan to explore sep's idea in the next few days.
